Answer:
75°
Step-by-step explanation:
the sum of the interior angles is always 180
43+62= 105
180-105=75
Answer:
q = 7
Step-by-step explanation:
4q + 9 = 37
If a letter and a number are together it means multiply.
<em>Substitute 7 into the equation:</em>
4(7) + 9 = 37
28 + 9 = 37
So q must equal 7
Answer:
Step-by-step explanation: d
Answer:

Step-by-step explanation:
We require to find the third side of the triangle.
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x represent the third side, then
x² + 15² = 17², that is
x² + 225 = 289 ( subtract 225 from both sides )
x² = 64 ( take the square root of both sides )
x =
= 8
